Audio power amplifiers work by taking a low-power audio signal and boosting it to a level strong enough to drive loudspeakers, allowing sound to be heard at higher volumes. They achieve this by using electronic components such as transistors or vacuum tubes to increase the amplitude of the input signal without significantly altering its original waveform. The amplified output is then delivered to speakers, which convert the electrical energy into sound waves.
